Dear Sir:
This letter, provides you with the results of a safe shutdown analysis and conceptual design for Alternate Shutdom capability, as required per Table 3.1 of the safety evaluation supporting Amendment No. 35 to our operating license.
Th a four day delay in submitting our response is due to additional time that was required to verify the accuracy of a computer code which was recently developed by Boston Edison Company to search the cable and raceway schedules to compile a list of components necessary to achieve a safe shutdown.
Item 3.1.18 Alternate Shutdown Capability An alternate shutdown system will be provided, independeat of cabling and equipment in the cable spreading room.
Response
A. Analysis
}~'0 044 An analysis was conducted to determine the capability to accomplish a safe plant shutdown with total loss of function ,
of the cable spreading room (CSR) due to an assumed fire. '
The following assumptions were made:
- 1. No analyzed accident occurs concurrently with a fire in the CSR.
- 2. The most severe natural phenomena do not occur concur- t h
i rently with a fire in the CSR.
- 3. Safety related component failures do not occur concur- 6 rently by with a the fire. fire in the CSR, except as directly caused '[()g 79101103F6

- 4. Abnormal r .erational trsnsients, as defined in the FSAR Appendix ' :an occur concurrently with a fire in the CSR.
- 5. One of the redundant safety divisions in the CSR is conservatively assumed to be functional during the initial period of twenty minutes from the time a fire is detected and the emergency shutdown procedure is -
initiated. This is based on 1) the defense-in-depth fire protection presently available in the CSR in the form of automatic smoke and heat detectors, automatic CO2 suppression system, fire barrier protection and spatial separation between safety division raceways,
- 2) proposed coating of all PVC insulated cables, all redundant rafety Division B exposed cables and the bottom part of all lower most cable trays with fire retardant material, and 3) encasing safety Division B power conduits in a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> enclosure to assure their functionability Isolation of all switches located in the local isolation panels will be accomplished during this time period.
- 6. Spurious operation of equipment and switchgear may occur due to a fire in the CSR if the control ettcuits pass through the CSR.
- 7. Three plant operators will be available to implement the e=ergency shutdown procedure.
The safety related equipment and switchgear required to be operable for safe shutdown have been identified (see Attached Table 1). The safety related equipment and suitchgear which are not required to be operable for safe plant shutdown, but whose spurious actuation could prevent the accomplishment of a safe shutdown have been identified as well (see Attached Table II).
Eaceway layouts and circuit schedules have been reviewed to determine the power, control, and instrumentation cables ;
that are associated with safety-related safe shutdown equip- .
=ent listed on Tables I and II, which pass through the cable spreading room. The review has identified the equipment for which spurious activation can be prevented (or operability can be achieved) by deenergizing (or energizing) a switchgear breaker. In addition,a list of components, for which a design modification is required to assure their operability, was generated (see attached Table III).

BOSTON E* DIS D N COMPANY Mr. Thomas A. Ippolito, Chief October 5, 1979 Page 3 B. Conceptual Design A design has been formulated to install L'olation switenes for safccy-related equipment that will provide tne capability for the plant operators to reach a safe shutdown condition indep-endent of the CSR and control room panels.
These switches will isolate their associated equipment from .
the CSR cables and thus transfer control from the control room to the local emergency shutdown stations outside the CSR. The local emergency shutdown panels and isolation switches will be seismically qualified and will be located as close as practical to the equipment or switchgear they serve.
Manual operator actions will be relied upon when feasible; otherwise operation will be by electrical means from the local emergency shutdown stations in the plant. Spurious actuation of equipment and usitchgear that are not required to coerate but c.'uld adversely affect plant safe shutdown will be prevented by deenergizing appropriate breakers and/or control circuits.
An emergency shutdown procedure, vhich is compatible with the design modifications and plant operator availability will be prepared to coordinate the opurator actions required to accomplish a safe plant shutdown.
All local emergency shutdown stations will be provided with key-locked doors or switches to insure that plant safety is not compromised during normal operation. In addition, an indicating light will be provided on the outside of each emergency shutdown panel which will be illuminated when all switches are in their
" Normal" plant operation positions. This status can be regularly monitored by plant operators. The control room position or status indicating lights for equipment and switchgear also serve to verify proper isolation switch position.
Two sketches showing the schematic diagram of a typical control circuit are attached:
- 1. Drawing E-lic shows existing schematic of RBCCW pump P202A.
- 2. DCN B2 to E-176 shows the same schematic with isolation switch located in one of the emergency shutdown panels.
Should you have any questions on this subject, please do not hesitate to contact us.
Very truly yours,
